Screen flicker debugging method, apparatus and system of display panel

Abstract

The present application provides a screen flicker debugging method of a display panel, an apparatus and a system. The display panel includes a first common voltage and a second common voltage. The voltage difference between the second common voltage and the first common voltage is configured as a reference voltage for deflection of the liquid-crystal molecules. The screen flicker debugging method of the display panel includes: acquiring a refresh rate interval of the display panel, and determining a minimum refresh rate; controlling the display panel to display a flickering picture with the minimum refresh rate; adjusting the reference voltage and acquiring flickering values of the flickering picture at different reference voltages; and determining the minimum flickering value and setting the corresponding reference voltage as the optimal reference voltage for the display panel. The flickering phenomenon of the display panel at high and low refresh rates is reduced.
